Hi Jukka,
I wonder if this can help:
In Java:
*SRSInfo srsInfo = ProjUtils.getSRSInfoFromLayerStyleOrSource(layer); *where
layer is Layer.class
(Actually OJ reads Layer.class SRS, if available from tag file or from
auxiliary (PRJ/AUX/AUX.XML) file, on loading that file. SRS info is saved
as SRSStyle)
*String source = srsInfo.getSource();*
It gives back where SRS info are islocated
for instance:
"C:/Folder/file.prj"
or
"Geotiff tag"
*String SRS = srsInfo.toString();*
it gives back a string with minimum SRS info
"EPSG:32632 WGS 84 UTM zone 32N [metre]"
Eventually all those info can be separated:
*srsInfo.toString().getRegistry* -->"EPSG"
*srsInfo.toString().getCode *-->"32632"
*srsInfo.toString().getDescription* --> "WGS 84 UTM zone 32N"
*srsInfo.toString().getUnit* --> "metre"
The method works also for RasterImageLayer.class
